Overview
The ARRMA Button Head Screw M4x20mm (4) Z-ARA-2258 is an essential replacement part for maintaining and servicing your ARRMA RC vehicle. Whether you own an ARRMA 1/10 FURY 223S BLX Brushless 2WD Short Course Truck or any compatible ARRMA model, these precision-engineered fasteners are the perfect items to keep on hand for routine maintenance, repairs and upgrades. As an RC car UK enthusiast, you'll appreciate the quality and reliability that ARRMA brings to every component, including these high-performance screws that ensure your brushless RC truck stays in peak condition.
Button head screws are fundamental components in RC vehicle construction and maintenance. Unlike standard screws, button head fasteners feature a distinctive rounded, domed head design that provides excellent grip for hex drivers whilst maintaining a clean, professional appearance on your model. These M4x20mm screws are specifically designed to fit the precise requirements of ARRMA vehicles, offering the exact thread pitch, diameter and length needed for critical assembly points on your ready to run RC machine.
When you're building, repairing or fine-tuning your RC model, having spare screws in the correct specification is invaluable. Stripped screws, lost fasteners and thread damage are common occurrences in the demanding world of RC motorsport, whether you're bashing in the garden, racing on a track, or exploring challenging outdoor terrain. This pack of four M4x20mm button head screws ensures you always have replacements on hand, keeping your RC car UK-ready and competition-fit at all times.
Key Features
- Strong Steel Construction — These button head screws are manufactured from durable steel material that resists corrosion, maintains consistent thread integrity and provides long-lasting durability even in demanding RC applications where vibration and impact forces are constant.
- Precision Manufactured Threads — Each screw features precision-engineered threads that engage smoothly and securely with corresponding holes in your ARRMA vehicle, enabling fast and easy maintenance without cross-threading or stripping, which would otherwise compromise the structural integrity of your RC model.
- M4 Hex Head Size — The M4 metric specification with standard hex head design fits perfectly with standard RC hobby tools, ensuring you can tighten and loosen these screws quickly and reliably without requiring specialist or unusual driver sizes that might not be in your toolbox.
- 20mm Optimised Length — The 20mm length is precisely calculated to reach the critical fastening points in ARRMA vehicle construction where these screws are required, ensuring proper clamping depth and load distribution across assembled components.
- Button Head Profile — The distinctive rounded button head design provides superior grip surface for your hex driver, reduces the risk of driver slippage and damage, and gives your RC vehicle a professional finished appearance compared to standard pan head or countersunk alternatives.
- Pack of Four — Supplied in a convenient multipack of four screws, this quantity ensures you have spares available for maintenance, repairs, and potential future replacements, reducing downtime and keeping your RC car ready for action.
- Black Colour Finish — The black finish provides a professional appearance that matches standard ARRMA component aesthetics, whilst also offering subtle corrosion resistance to help maintain appearance and performance over extended use periods.
Technical Performance
These ARRMA button head screws represent the quality standard expected from ARRMA's range of replacement parts and accessories. Manufactured to precise M4 metric specifications, these fasteners deliver reliable performance in the demanding environment of RC vehicle operation. The steel material selection provides excellent strength-to-weight ratio whilst maintaining the precise dimensional tolerances required for secure fitting in ARRMA vehicles. The precision-manufactured thread design ensures that each screw engages smoothly without binding or resistance, which is essential for achieving consistent clamping force across multiple fastening points on your RC model. Whether you're performing routine maintenance on your brushless RC short course truck, replacing damaged fasteners after an accident, or upgrading internal components, these screws deliver the reliability and consistency that serious RC enthusiasts expect. The 20mm length is optimised for ARRMA's engineering specifications, ensuring that fasteners reach the proper depth without bottoming out or creating excessive protrusion that might interfere with moving components or suspension geometry. The M4 hex head size is compatible with standard 3mm hex drivers found in most RC tool kits, making these screws universally accessible for any RC car UK owner regardless of their current tool collection.

Frequently Asked Questions
- What ARRMA vehicles are these M4x20mm button head screws compatible with? — These screws are compatible with multiple ARRMA models including the 1/10 FURY 223S BLX Brushless 2WD Short Course Truck RTR in both green and blue variants (part numbers C-ARA3521T2 and C-ARA3521T1). However, they are also suitable as general replacement fasteners for any ARRMA vehicle that requires M4x20mm button head screws, making them a versatile addition to your RC spares collection.
- Are these screws suitable for beginners working on their first RC vehicle? — Yes, absolutely. These button head screws are straightforward to install and remove, requiring only a standard 3mm hex driver that comes with most RC tool kits. Beginners will appreciate the precision-manufactured threads that make assembly easy without risk of cross-threading, and the 20mm length provides confident engagement depth without requiring specialist knowledge.
- Can I use these screws as replacement parts for damaged fasteners? — Yes, that is the primary purpose of this product. If you have stripped screw holes, damaged fasteners, or missing screws on your ARRMA RC vehicle, these replacement M4x20mm button head screws provide an exact specification match that restores your vehicle to factory condition. The pack of four ensures you have multiple spares.
- What is the difference between button head screws and other screw types? — Button head screws feature a distinctive rounded, domed head design compared to standard pan head or countersunk alternatives. This rounded profile provides better hex driver engagement, reduces the risk of driver slippage and rounding damage, and offers a more professional appearance. For precision RC applications, button head screws are preferred because the design minimises risk of fastener damage during assembly and disassembly.
- How often should I replace these screws on my ARRMA RC vehicle? — In normal use, these screws should provide long service life thanks to their steel construction. However, you may need replacements if you experience thread stripping, accidental loss of screws during maintenance, or occasional damaged fasteners from impacts. Keeping spare M4x20mm button head screws ensures you're never left waiting for replacement parts during maintenance sessions.
- Are these black screws rust-resistant? — The steel material with black finish provides good corrosion resistance suitable for typical RC hobby use. However, like all steel fasteners, they should be kept dry and not exposed to prolonged moisture. If you regularly run your RC car in wet conditions, consider storing these screws in a dry location and inspecting them periodically for any corrosion development.
